I've been trying to get the enclosure lick revved up since taking your class at DFNW last year - I haven't made a daily routine of it, but I play probably 40 reps at least 2 to 3 times a week among other finger excercises. I'm to the point now where 150bmp is a snooze and 187 is uncomfortable but clean and repeatable and 208 is the fastest I can go. I get about 1 in 5 truly "clean" reps at 208.
Just out of curiosity I played the audio sample from your website last night and clocked you at 333bpm with my metronome (if you assume eight notes in 4... If you assume you're playing it in 2, then you're slightly over 186bpm and my fastest tempo is about 104bpm)
Is that you? Did you speed it up?
Damn, boy. You can get a speeding ticket for that.
You get one chance to enjoy this day, but if you're doing it right, that's enough.
